This is a must-see and one of the best documentaries - and films - of this year.

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

The film may be flawed, but its message is not.

.Like the great film, it's made with a great deal of visible affection both in front of and behind the camera.
